fix(release): Fix release-plz dirty-tree errors from Ruby binstubs (microsoft#547)

Ruby binstubs were checked in, but ignore via .gitignore **bin pattern.
This causes release-plz to think that the source tree is dirty.

The binstubs are deleted from source repo since they are always regenerated by bundler.
Also simplizy release-plz to focus only on the core crate.
